Thermostat Mode Automation Not Firing

Configuration Z-Wave
,
1

I have a simple automation (see below) that changes the HVAC mode to ‘heat’ when the thermostat’s temperature dips below 73° and the existing mode is set to ‘cool’. This morning, my house temperature hit 72° and the automation did not fire. If I manually execute the automation, it works fine.

Note: The YAML was created via the built in interface

    type: set_hvac_mode
    hvac_mode: heat
  mode: single

Any help would be greatly appreciated.

Thanks,

It appears the following condition is preventing it from running:

  - condition: device
    device_id: 1e5b5eac010611ebb43a31b3f43484fb
    domain: climate
    entity_id: climate.honeywell_th6320zw2003_t6_pro_series_thermostat_mode
    type: is_hvac_mode
    hvac_mode: cool

When I removed it, it started to work. Has anyone else had this happen? I can view the hvac_mode state just fine in the Developer Tools.

I decided to pool based on a time interval, and am now using the following logic:

- id: '1601243782394'
  alias: 'Thermostat: Switch to Heat'
  description: ''
  trigger:
  - platform: time_pattern
    minutes: /5
  condition:
  - type: is_value
    condition: device
    device_id: 1e5b5eac010611ebb43a31b3f43484fb
    entity_id: sensor.honeywell_th6320zw2003_t6_pro_series_thermostat_temperature
    domain: sensor
    below: 73
  action:
  - device_id: 1e5b5eac010611ebb43a31b3f43484fb
    domain: climate
    entity_id: climate.honeywell_th6320zw2003_t6_pro_series_thermostat_mode
    type: set_hvac_mode
    hvac_mode: heat
  mode: single

I figured having this check every 5 minutes wouldn’t be overkill, and result in less calls to my thermostat. Speaking of, if the mode is already set to ‘heat’, would Home Assistant even send the mode change to my thermostat?
